My invention relates to cleaning and polishing machines for oranges andother fruit; and it has for its objects to provide a simple andetficicnt construction of machine through which the fruit is fedautomatically; to proinclined bars 6.

vide means whereby the fruit is rubbed or polished by the differentialrotations of cooperating rolls, and to provide a cheap and efficientsubstitute for the polishing brushes usually employed in ueviccs of thisclass.

With such general Objects as the above in view the invention consists incertain features of construction hereinafter specified and particularlypointed out in the claims.

Referring to the drawings, Figure 1 is a perspective View of a machineembodying my invention. Fiz. 2 is a vertical longitudinal sectional viewof the same. Fig. 3 is a transverse sectional view. Fig. 4 an end view.

Like numerals of reference indicatelike parts in all the figures of thedrawings.

In the practice of my invention I employ any desired construction offramework, and have herein illustrated one simple formnvhich I willproceed to describe.

I employ opposite pairs of vertical posts 1, connecting, said pairsintermediate their ends by transverse and preferably cnstnnetal frames2, and at their iovxer ends by tie-bars corresponding longitudinallydisposed tiebars 4 serving to connect the pairs ct posts or standards 1.intermediate standa ds 5 risea't the sides of the frame and are boltedtothe tie-bars 4, and the said standards 5 project above theircompanions 1 and are connected to a pair of said end standards by-Arrnnged upon the inclined bars 6 is an inclined hopper 7, into whichthe fruit is to be introduced, and the said hopper is provided at itslower end with a discharge-chute 8 adapted to discharge directly overthe cents and at one end of the machine. A cross-bar 9 sun-mounts thoseposts or standards 1 adjacent to the lower end of the hopper 7, and fromthe casting at one side of its center there projects astubshaft 10,

upon which a spur-gear 11 is located, the same having a handle 12projecting from its outer face by which it may be manually 0p erated. V

The cross-frame 2 at that end of the machine adjacent to the gear 11 isarranged above the plane of the frame 25 at the opposite end of themachine, and each is provided with a -plurality of-journal-boxes 13, inthe present instance two, one at each side of the center thereof, andsaid journalboxes receive the axes 14 of as many longitudinally disposedparallel polishing-rolls 15, the same being inclined contrary to theinclination of the hopper 7. One of the rolls has its shaft or axis Hprovided with asmall spurgear 16, while the other has its axis providedwith a larger spur gear 17, but each, however, meshes with and is drivenby the waster-genr 11, so that the rolls are driven in the samedirection but at ditferent rates of speed. Each of these rolls isprovided with a covering or polishing material 18, of sheepskin,

and between the rollsI prefer tolerate a longitudinal rest-barit), thesame having its ends connected to the opposite transversely disposed endcastings 2, and therefore partially closing the space between the rolls.Of course any number of rolls may he provided, their fnnctionsnndoperations being substantially the same, but I prefer to employ but two,in that I gain the best results thereby. A bottomless guide-box 2.) isarranged over the rolls and connected to the opposite transverseend-bars of the framework, the said guide box having its opposite sidewalls slightly elevated above the rolls, so as to give them free motion.The guide-box is inclined so as to be parallel to the rolls, and ispreferably provided with aminged cover 21, which, together with the interior surfaces of the sides of the box, is covered with a lining 22,also of sheepskin.

This completes the construction of the machine, and the operationthereof is as follows:'lhe oranges, or other fruit, are fed into thehopper 7, and by the inclination of the same, are caused to seek thedischarge 8.

- bruising, abrading, or other injurious sheets.
